Definitions

  • the present invention provides means for unattended operation for a long time of period by removing contaminants with a cutting tool such as a grinding tool when contaminants adhere to a nozzle of a laser processing machine.
  • Patent Document 1 discloses a machine having a brush for removing dross which adheres to a nozzle.
  • some melt (sputtered material) in the processing flies above a work surface, due to the pressure of an assist gas for example, and adheres to a bottom surface of a nozzle, which makes a gap between the bottom surface of the nozzle and the upper work surface non-uniform.
  • the patent document above described discloses a copy operation to control the position of a laser processing tool in the Z axis direction which records a Z axis coordinate by bring a nozzle into contact with a touch sensor.
  • the patent document also discloses a method for removing contaminants such as dross adhering to a nozzle by bringing a nozzle tip to a brush so that a circular motion of the nozzle removes the contaminants.
  • the present invention provides a device having a polishing device to polish a nozzle without moving the nozzle.
  • a laser processing machine comprises: a bed; a pellet disposed on the bed to support a work; a column which is controlled to move along the X axis, the X axis being the longitudinal axis of the bed; a saddle which is supported by the column and is controlled to move along the Y axis, the Y axis being perpendicularly crossing the X axis; a processing head which is supported by the saddle and is controlled to move along the Z axis, the Z axis being perpendicular to a plane defined by the X axis and the Y axis.
  • the present invention provides a nozzle polishing device comprising a melt removing device for removing melt with a grinding tool, the melt adhering to a tip nozzle of a laser processing tool mounted to the processing head as basic means.
  • a copy function is stabilized so that a gap between a bottom surface of a nozzle and an upper work surface becomes uniform, imperfections in a processing such as dross forming are not caused, which stabilizes the processing and makes an unattended operation for a long time of period possible.
